Newer 802.11g and 802.11a devices need b43. It is safe to include both b43 and b43legacy as the underlying glue layer will automatically load the correct version for your device. This driver uses V3 firmware, which must be installed separately using b43-fwcutter. This driver can be built as a module (recommended) that will be called "b43legacy". If unsure, say M. # Auto-select SSB PCI-HOST support, if possible config B43LEGACY_PCI_AUTOSELECT bool depends on B43LEGACY && SSB_PCIHOST_POSSIBLE select SSB_PCIHOST select SSB_B43_PCI_BRIDGE default y # Auto-select SSB PCICORE driver, if possible config B43LEGACY_PCICORE_AUTOSELECT bool depends on B43LEGACY && SSB_DRIVER_PCICORE_POSSIBLE select SSB_DRIVER_PCICORE default y # LED support # This config option automatically enables b43legacy LEDS support, # if it's possible. config B43LEGACY_LEDS bool depends on B43LEGACY && MAC80211_LEDS && (LEDS_CLASS = y || LEDS_CLASS = B43LEGACY) default y # This config option automatically enables b43 HW-RNG support, # if the HW-RNG core is enabled. config B43LEGACY_HWRNG bool depends on B43LEGACY && (HW_RANDOM = y || HW_RANDOM = B43LEGACY) default y config B43LEGACY_DEBUG bool "Broadcom 43xx-legacy debugging" depends on B43LEGACY default y help Say Y, because this information will help you get the driver running. This option generates a minimum of log output. config B43LEGACY_DMA bool depends on B43LEGACY config B43LEGACY_PIO bool depends on B43LEGACY choice prompt "Broadcom 43xx-legacy data transfer mode" depends on B43LEGACY default B43LEGACY_DMA_AND_PIO_MODE config B43LEGACY_DMA_AND_PIO_MODE bool "DMA + PIO" select B43LEGACY_DMA select B43LEGACY_PIO help Include both, Direct Memory Access (DMA) and Programmed I/O (PIO) data transfer modes. The mode actually used is selectable through the module parameter "pio". With pio=0 as a module parameter, the default DMA is used, otherwise PIO is used. If unsure, choose this option. config B43LEGACY_DMA_MODE bool "DMA (Direct Memory Access) only" select B43LEGACY_DMA help Only include Direct Memory Access (DMA). This reduces the size of the driver module, by omitting the PIO code. config B43LEGACY_PIO_MODE bool "PIO (Programmed I/O) only" select B43LEGACY_PIO help Only include Programmed I/O (PIO). This reduces the size of the driver module, by omitting the DMA code. Please note that PIO transfers are slow (compared to DMA). Also note that not all devices of the b43legacy series support PIO. You should use PIO only if DMA does not work for you. endchoice |
